Oligonucleotides: "Polymers made up of a few (2-20) nucleotides. In molecular genetics, they refer to a short sequence synthesised to match a region where a mutation is known to occur, and then used as a probe (oligonucleotide probes)." [[3]]

Dehydrogenase: "Enzyme that oxidizes a substrate by transferring hydrogen to an acceptor that is either NAD/NADP or a flavin enzyme. An enzyme that is used to remove hydrogen from its substrate, which is used in the cytochrome (hydrogen carrier) system in respiration to produce a net gain of ATP." [[4]]

Synthetase: "Enzymes of class 6 in the e classification, catalyse synthesis of molecules, their activity being coupled to the breakdown of a nucleotide triphosphate." [[5]]
